while it is true that she is probably not the heaviest of the 2nd gen members, but she is the one that has gained the most weight among the 2nd gen when the rest of the 2nd gen has been losing weight. If you look at just how small the girl is in the beginning you'd realize that Amimi was really chubby at the time and during the 3rd gen era, Umeko was really gaining weight a bit, but as the 4th gen step in, the rest of the 2nd gen has been losing a lot of weight, except for Serina.

I dunno why, Serina is less popular in Nikkisei, is it because she's a quiet type-girl??? (compare with Umeko, Amimi, Nao). Didn't you guys see in Idoling!!! episodes that Serina sometimes get "cold" responses from the other member?? I saw sometimes she's being ignored too.

I think she have started her career in Idoling!!! with great experience record, such as Oha Star girl. As i know, she was also child actress (like Ashida Mana). Also her love of anime should be advantages to become more popular (member).

IMO she's cute, combine with Chubby looks She's still young (youngest in Nikkisei), also have a lot of potential. That's why she's one of my fav. members (beside Kaorun, Ruri & Maipuru)

When she first joined, she was super outgoing and very "in your face," playing the whole younger sister kinda character. I think that, combined with her love for bizarre anime that only the hardcore otaku like, made a lot of members tease her to the point where she just doesn't talk anymore. She also used to be fairly skinny in the beginning. Looking back, I think the newer gens entering the group also contributed towards her being less and less outgoing.

I also think that her love for non-mainstream anime is having the effect of the others thinking "ugh, she's going otaku again, we're not interested in that".While Maipuru & Sakacchi are also manga/anime fans, they are mainstream: Dragonball, One Piece, Detective Conan.

Nevertheless, I like Serina, I like her character and I think she's very cute. Which is why she was one of the 5 members I went to handshake at the MAMORE!!! handshake.

I do notice that she gets a little more MC'ing to do at Nicohachi lately.

Serina Nagano turns 18 years old today, 9月29日-She is no longer a little kid, but has grown into a beautiful youngwoman! Hoping that Serina has a great day with her family and friends, and that the upcoming year brings her much activity atwork, and much joy and happiness in life!!!
